HERBERT M. PIKEK 4 BY fl-tOIl/f United States Patent 3,250,276 FILE BOX 9R CQNTAINER Herbert M. Piker, Wyoming, Ohio, assignoi: to The Hamilton-Sketch Corporation, Hamilton, 01110, a corporation of Ohio Filed May 16, 1962, Ser. No. 195,072 Claims. (Cl. 129-26) This invention relates to improvements in file boxes or containers, that is, file boxes, as generally referred to,

of the kind made of metal, generally, for home use or for use in filing and keeping personal papers with said boxes to a size to file standard letters, a size for filing checks, and similar material. The invention is particularly concerned with the provision of a backup member, frequently referred to as a follower or compressor, in combination with the box, for holding the papers in an upright position when the said papers are less than the full capacity of the box or container.

Broadly, moveable followers, backup members, or compressors are old in filing drawers or the like to insure the papers standing upright. In the past these constructions have been substantially independent mechanisms without regard to the actual construction of the filing container.

The principal object of the present invention, therefore, is the provision of a filing container in the form of a box with which is utilized a follower, backup member, compressor, or the like and in which such parts, per se, cooperate with one another.

A further object of this invention is the provision of a follower, backup member or compressor in the form of a compartment into which the papers, checks, cancelled vouchers, or the like may be placed for subsequent desirable filing with respect to one another ahead of said follower, backup member or compressor.

It is also an object of this invention to provide a construction for accomplishing the foregoing objects that is economical to produce and acquire thereby enabling the ready production of the combined filing container and follower part.

Other objects and advantages of the present invention should be readily apparent by reference to the following specification considered in conjunction with the accompanying drawings forming a part thereof and it is to be understood that any modifications may be made in the exact structural details there shown and described, within the scope of the appended claims, without departing from or exceeding the spirit of the invention.

FIG. 14 is a perspective view of a follower, backup member or compressor of the form illustrated particularly in FIGS. 9 and 10.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

The invention is illustrated in the drawings in connection with a file box or container of a size primarily intended in filing cancelled checks or vouchers and is therefore relatively shallow with respect to its width and length. It is obvious however that the herein disclosed and hereinafter described elements and construction can be modified so that a relatively deep filing box, container, or the like, may be produced without in any wise deviating from the principles and purposes of the present invention.

Specifically the box illustrated in the drawings comprises a box or container, per se, indicated in its entirety by the reference numeral 10 having at its upper end a cover 11 preferably hinged thereto in any suitable or desirable manner by a hinge pin 12. The cover is adapted to be latched and locked in its closed position through a conventional latch and lock mechanism indicated in its entirety by the reference numeral 13. As usual the latch and lock comprises a keeper 14 carried by the front wall of the box 10 together with a latch 15 carried by the front wall of the cover 11 to cooperate with the keeper 14.

The file boxes or containers as contemplated by the present invention are generally provided with a carrying handle, not shown in the drawings, and which may take any suitable or desirable construction, said carrying handle in no wise forming a part of the present invention.

The cover 11 is formed of a single piece of material including the cover or top panel 16 from opposite edges of which depend a front flange 17 and a back flange 18. correspondingly, the top or cover panel 16 has depending from its remaining edges side flanges 19 and 20. The

front and back flanges 17 and 18 have each extending from its opposite ends a tab 21 adapted to overlap the adjacent edge of a side flange and be secured to one another by spot welding or the like.

As illustrated in the drawings, particularly FIG. 2, the back flange 18 is of greater height than the front flange 1'7 with its lower end rolled to provide an eye, as at 22, through which the pivot pin or rod 12 projects.

The front flange 17 and the side flanges 19 and 2t each has its lower edge rolled, as at 23, to provide a finished edge to said panels.

The box, per se, is formed of three separate pieces or parts with the main piece or part clearly illustrated in FIG. 6 and comprising a main or bottom panel 24 from the forward edge of which upstands the box front panel 25 while from the opposite edge of which upstands the box back panel 26. The front panel 25 upstands to an inwarda 1y projecting shoulder 27 and has an inner upwardly projecting flange 28 whose upper end is rolled to provide a finished edge. Shoulder 27, as seen in FIG. 2, is engaged by the cover front flange bead or roll when the said cover is in itsclosed position.

The box back panel 26, likewise, upstands to an inwardly extending shoulder 29 from which upstands a back flange 30 having its upper end rolled to provide a finished edge therefor. It should be noted that the shoulder 29 is a greater distance from the upper edge of the back wall panel 26 than is the shoulder 27 from the upper end of the front wall' panel 25 for the purpose of accommodating the greater length of the cover back flange and its hinge bead 22. The reason for this construction, as will later be clear, the hinge pin 12 is below the box shoulder whose normal height is as the front wall shoulder 27.

The box bottom or panel 24 has at its remaining opposite edges upstanding side wall attaching flanges 31 and 32 each of which at its opposite ends is provided with an inwardly offset shoulder as at 33 and 34, each followed by a corner piece 35 and 36 inwardly disposed by its offset shoulder 33 or 34.

The box front and back are each provided at its ends with an inwardly extending integral flange 37 and 38 which is of a width substantially equal to and disposed in the space of the offset box side corner piece as clearly illustrated in FIGS. 4 and 6. It should be noted that each of the corner pieces 35 and 36 is offset an amount such that the space of the offset, as effected by the shoulder 33 -or 34, is such that it is not filled by its flange 37 or 38 but that a pocket exists between the inner opposed faces of said offset corner piece and opposed flange.

Each side wall attaching flange 31 and 32 is similarly formed wherefore a pocket is provided in each corner .of the box bottom or panel 24.

It should be noted that the upper ends of the back wall flanges 37 and 38 are each provided at its upper end with an aperture 39, see FIG. 6, which are in axial alignment with one another and in alignment with the cover back flange head or eye 22 and through which axially aligned apertures and eye the pivot pin or red 12 extends in effecting the hinge connection of the cover to the box, per se. Any suitable or desirable means may be employed for retaining the hinge pin in its operative position, such as upsetting or flanging the ends of the said hinge pin.

Cooperating with the box part of FIG. 6 are the box side wall parts which are substantially duplicates of one another and one of which is most clearly illustrated in FIG. 7, and a description of which will suflice for both side walls. As illustrated in said FIG. 7 the said box side wall comprises a body portion or wall panel 44) having near its upper end an inwardly extending shoulder 41 and an upwardly extending flange 42 with its upper edge rolled, as at 43, to provide a finished edge. The said shoulder 41 upon positioning and assembly of the side wall part with the main box part is in horizontal alignment with the shoulder 27 of the box front wall 25, and when both side wall parts are in assembled positions, has resting thereupon the rolled edges 23 of the top side flanges 19 and 20.

The side wall part has at its lower end an inwardly olfset shoulder as at 44, with an inwardly offset flange 45 forming the lower end of the said side wall part body portion or wall panel. The offset flange 45 has at its lower end an inwardly projecting flange or ledge 46 at right angles to the side wall body portion.

The said side wall part body portion or panel 40 has inwardly of its lateral ends inwardly projecting offset shoulders as at 47 and 48 with vertically extending oflset end flanges 43 and 50 at the inner edge, respectively, of the offset shoulder 47 and 48. As will be seen from FIG. 7 the bottom inwardly offset flange 45 is of less length than the distance between the end offset shoulders 47 and a roll 61.

48 thereby providing a cutout portion or notch 51 and 52 between the ends of the offset flange and the vertically extending end flanges 49 and resulting in tabs 53 4 and 54 at the lower ends of said oifsets end flanges 49 and 50 below the side wall body portion or panel 40.

In assembling the side wall parts with the box bottom front wall-back wall part, the said side wall parts are so positioned that the box bottom side wall attaching flanges 31 and 32 respectively enter the space effected by the side walls offset shoulders 44 wherefore said bottom side wall attaching flanges 31 and 32 are exteriorly of the box. correspondingly the box front wall and back wall lateral end flanges 37 and 38 enter the spaces effected by the side walls offsets shoulders 47 and 48 and wherefore the offset end vertical flanges 49 and 50 are internally of the box with the tabs 53 and 54 at the lower ends thereof in the pockets formed between the inner surfaces of corner pieces 35 and 36 and the opposed back Wall and front wall flanges 37 and 38.

Since the box bottom side wall attaching flanges 31 and 32 are exteriorly of the side walls and the said side walls lower offset, or inset, flanges 45 are interiorly of the box, the horizontal flanges or ledges 46 of said box side walls are likewise inwardly of the box assembly. It should be noted that the height of the side walls offset, or inset, flanges is less than the vertical height of the bottom side wall attaching flanges 31 and 32 wherefore upon assembly the'side wall parts are finally positioned by having their offset shoulders 44 on the upper edges of the bottom side wall attaching flanges 31 and 32 with the result that the said side wall horizontal flanges or ledges 46 are upwardly of the box bottom panel 24 thereby providing a passageway or channel 55 below the horizontal flanges or ledges 46.

After assembly the contacting portions of the box parts, namely, the inset flanges 49 and 50 of the side wall parts and the lateral flanges 37 and 38 of the box front and back walls are secured to one another, as by spot welding. The inset side wall parts flanges 45 are similarly spot welded to contacting box bottom side walls flanges 31 and 32. The said box parts are thereby rigidly connected to one another with their front, back and side walls upstanding from the bottom panel 24 and with each side wall having extending longitudinally thereof a channel 55 beneath each side wall horizontal flange or ledge 46 and which channels open interiorly of the box and toward one another.

Disposed within the box is a follower, backup member, or compressor indicated in its entirety by the reference numeral 56. Basically the part 56 is U-shaped in cross-section and primarily comprises a base 57 from the forward edge of which upstands a wall 58 which is of considerable height with respect to the depth of the box, per se, and with its upper end finished as by rolling as at 59. The part 56 at the other side of its base 57 is provided with an upstanding menrber, which, as will later be made clear, may have different heights, that shown in FIGS. 3 and 4, being of the same height as the front wall 58 and with said back wall being identified by the reference numeral 60 with its upper end finished as by With this construction there is provided a space or compartment 62 between the walls 58 and 60, for a purpose subsequently to be made clear.

As seen in FIGS. 3 and 4 the said part 56 is of a length just short of the distance between the inner or free edge of the box side wall horizontal flanges or ledges 46 wherefore said part 56 with the lower surface of its base 57 disposed on the upper surface of the box bottom panel 24- may he slid or moved toward and from the box front wall 25. v

The said part 56 may be adjustably retained in any of its positions of adjustment by any suitable or desirable means, that shown in FIGS. 2, 3 and 4 comprisinga flexible plate or strap 63 rectangular in plan and without any embellishments whatsoever, as seen in FIG. 8. This plate or strap 63 is cut to a length' greater than the length of the part 56, particularly of a length greater than the length of the follower, backup member or compres 'sor base 57, and of a width slightly less than the width of the said base 57. The strap or plate 63 ,is of a length that when mounted in operative positions has its outer ends 64 and 65 respectively disposed in the passageways or channels 55 beneath the flanges or ledges 46 of the opposite box side walls. The said length of the strap or plate 63 is such that it can be shifted at an extreme position, either to the right or left, of that shown in FIG. 3 without releasing the other end from beneath its flange or ledge 46. In order to mount the parts in their operative positions the part 56 is first disposed on the box bottom panel 24 between the box side wall flanges or ledges 46 whereupon the strap or plate 63 is disposed within the space or compartment 62 of the part 56 with one end, end 64, for example, pushed under its side wall flange or ledge 46, bending or arching said strap or plate 63, if necessary, to insert the said end 64 into its passageway or channel 55. The strap or plate 63 is then bent or arched as shown in phantom lines at 66, in FIG. 3, whereupon the remaining end, end 65, for example, is then inserted into the passageway or channel 55 beneath the opposite side wall horizontal flange or ledge 46.

It will now be appreciated that the part 56 is secured to the box bottom panel 24 in such a way that it can be slid on said box bottom panel 24 toward and from the box front wall 25. The plate or strap 63 has inherent flexing and spring properties and the parts are so designed that a certain amount of yieldable clamping is effected by the strap or plate 63. In order however to fasten the part 56 in various positions of adjustment, the said part may be canted as illustrated in phantom lines at 67 in FIG. 4. This canting being effected until opposite corners of the part 56 are engaging the free edges of the side walls horizontal flanges or ledges 46.

By forming the part 56 with its front and back walls '58 and 60 of the same height, and as intimated above, there is provided between them the space 62 which conveniently provides a compartment into which papers, checks, vouchers, and the like may be placed for individual removal for alphabetical, numerical or other systematic filling in the space between the said part front wall 58 and the box front wall 25. Obviously this compartment need not be so employed but is provided for this purpose.

A combined follower, backup member, or compressor and securing mechanism is illustrated as a modification in FIGS. 9, and ll and comprises a part substantially identical in all respect with the part 56 and as having a base 57 with a front wall 58' and a back wall 60' each with its upper end rolled, as, respectively, at 59' and 61' and with a compartment 62 between the walls 58 and 60'. The modified part 56' has projecting from the opposite ends of its base 57' a pair of ears 68 and 69 and which ears at each of the base 57' takes the place of the projecting ends 64 and 65 of the strap or plate 63, that is, said ears 6S and 69 enter the passageways or channels 55 beneath the side walls inwardly projecting horizontal flanges or ledges 46.

Obviously the part 56' cannot be flexed for inserting the said ears 68 and 69 into the passageways or channels 55. In this instance the spaces, see FIG. 9, 7t) and 71 between the opposite ends of the side wall horizontal flanges or ledges 46 and box front wall and back wall and 26 are employed for the purpose of operatively associating the box or container and the follower, backup member, or compressor.

In other words, and as illustrated in FIG. 9, the modified part 56' is placed in either of the positions thereof illustrated in phantom lines in FIG. 9, for example, the said part is placed in the phantom line position 72 at the upper end of said FIG. 9 which disposes the ears 68, from the opposite ends of the base 57', on the upper surface of the box bottom while the cars 69 are on the upper surface of the box side horizontal flanges or ledges 46. A forward movement, downward as respects the disclosure in FIG. 9, to the phantom line position 73 thereof, causes the said cars 68 to enter the passageways or channels 55 and to be disposed beneath the side walls horizontal flanges or ledges 46 while the cars 69 ride on the upper surfaces of said horizontal flanges or ledges 46. Movement of the part 56' to the bottom of FIG. 9, said phantom line portion '73, will dispose the said ears 69 beyond the side wall horizontal flanges or ledges 46 whereupon a reverse movement of said part 56 disposes the ears 68 and 69 each beneath its side wall horizontal flange or ledge 46, as illustrated in full lines in FIG. 9.

Obviously the said part 56' can be disassociated from the box upon the reverse operation from that above described.

In order to insure a yielding retainment of the part 56'- in its adjusted positions the said ears 68 and 69 are each, respectively, provided with an upwardly projecting ridge or rib 74 and 75 which, in effect, yieldably and frictionally clamp the ears between the opposed surfaces of the side walls horizontal flanges or ledges 46 and the box bottom panel 24.

In the event the said parts 56 or 56' is not desired to act as a compartment filing means, the back wall thereof may be substantially eliminated is shown at 76 in FIG. 13 and 77 in FIG. 14 respectively for the part 56 and 56'. It will be readily appreciated that the said modified parts as illustrated in FIGS. 13 and 14 will readily perform their function as a follower, backup member or compressor in a filing box or container.

From the foregoing, it is now believed obvious, that i there has been provided a mechanism and structure which accomplishes the objects initially set forth.
